some question about how to use ARM A15 of 66AK2H12

Other Parts Discussed in Thread: 66AK2H12, SYSBIOS

hi,

I am using 66AK2H12 EVM, I have some question  about ARM A15:

Q1: if the ARM A15 is running linux, can I develop the arm program on ccs6.0 on windows PC? If it is, after I buld the arm project and generate a .out file , can I run the  out  file on the linux system which is running on the  ARM A15?

Q2: I have known that I can create a A15 project  based on sysbios , If Q1 is true, can  I  run a out file which is based on sysbios on the linux system?

Q3:If I develop ARM A15 project, when I create ccs project, what device type shold I  choose?  66AK2H12 device or ARM cortexA15? I find that if I choose cortexA15, it can't find a arm project template based  on  sysbios , but  66AK2H12 can, what's difference betwen the two  device type for ARM?

Q4: when I create a 66AK2H12 device project, for arm project, it has a warning(both linux and windows), how can I avoid it. Here is the picture.

Best Regards,

Si

    Hi Si,

    A1: You can develop ARM program on windows CCS however you can not run the same from ARM A15 Linux.

    A2: As of now SYS/BIOS is not supported on ARM A15.

    A3: For ARM A15(Keystone II) CCS project, select ARM cortexA15 as device. For DSP(Keystone II) CCS project, please select 66AK2H12. As I said earlier, SYS/BIOS is not supported on ARM core hence there is no template project based on SYS/BIOS.

    A4: The 66AK2H12 device is for DSP project so please select the Compiler version TIv7.4.x.

    I hope this helps.

    Thank you.

    hi Rajasekaran K,

    Thanks for your reply.

    Q1: you said "You can develop ARM program on windows CCS however you can not run the same from ARM A15 Linux." If the out file which is built by ccs on windows can't run ARM A15 linux system,the ccs for ARM is just  considered as an editor, and it can not use for debuging linux program, is it right? 

    Q2:you said "SYS/BIOS is not supported on ARM core hence there is no template project based on SYS/BIOS."

    here is the picture when I create 66AK2H12  project.

    when I create a 66AK2H12 project, it automatic create two project，one for ARM(arrow1),one for DSP(arrow1),:choose arm project, there is a project  template in which there is sysbios for GNU target(arrow3).why?

    Regards,

    Si

    Hi Si,

    A1: The CCS shall be used to develop & debug standalone ARM A15 application.

    A2: I was referring to older version of CCS. I think you were using CCSv6.

    If the 66AK2H12 device is selected for creating a new  project, then user should be able to create project for DSP and ARM as shown above. As of now SYS/BIOS is not supported on ARM A15, the support to SYS/BIOS on ARM A15 will be included in MCSDK3.x soon however CCS has support to it.

    Thank you.

    hi Rajasekaran K,

    Thanks for your help, i have a another question, I have installed the mscdk 3.0, but it's example are all based on dsp,not for arm,if I use 66ak2h12,I want to use arm for network and srio and other task,I just want dsp for computting, not for another task. when you use 66ak  soc  ,what's your plan.
